#173097 - maybe... Responding to: ???'s previous message |
... Steve Taylor mentioned that magnetic field of 2 wires will be subtracted -placed in parallel - let say - for 1 meter , and sensor will be in the middle of that area. If wires are distanced on 5 cm - maybe in centre of that rectngular (1m x 5cm) field will be close to zero and will have two components - earth fiald and current's difference field.
I didnt read that somebody tryed this. Instead Hall sensor magnetoresistive sensor will be (probably) better choice - search for ZMY20, KMY20 parts for example. Resolution can be much better. But is this possible ..... Good luck! |
